Subject: mbox: add scrolling support and truncate control

Widget argument can now be a string (full path to the mbox) or a
table. In case of a table 1st field is full path to the mbox and 2nd
is maximum text lenght after which it will be truncated. If there is a
third field scrolling will be used - if so, 3rd field should be the
widget name.
